+Affiche les fichiers qui SONT des doublons, sous forme d'un script
+  permettant leur suppression.
+Pour afficher les fichiers qui ne sont pas des doublons, utilisez
+  showunique.
+
+Syntaxe : remdoubles dossier-où-chercher-les-doublons < md5sums
+
+Exemple :
+  md5sums contient :
+    604c442629170d4bee5804b13e9a587f  ./a/fichier_un
+    a3d0c4f97abec8c2ceaaf83020f00809  ./b/fichier_deux

+    7d4abe4e5104b71312ab56c2f341856e  ./b/fichier_pas_de_doublons
+  Si on lance "showdoubles < md5sums", il affichera

+    './b/fichier_XYZ'
